Abstract (en)

[origin: US2014223940A1] An air-conditioning apparatus includes a refrigeration cycle that includes an intermediate heat exchanger configured to exchange heat between a heat source side refrigerant and a heat medium different from the heat source side refrigerant, a heat medium circuit that includes at least one pump configured to circulate the heat medium related to heat exchange in the intermediate heat exchanger, a use side heat exchanger configured to exchange heat between the heat medium and air related to an air-conditioned space, and flow switching valves. A controller is configured to perform control to activate the pump to circulate the heat medium through the heat medium circuit when, during suspension of an air conditioning operation, the detected temperature of outdoor air is at or below a first predetermined temperature and a first predetermined period of time has elapsed since the pump was stopped.
